Purpose: To compare the safety and effectiveness of liver vein deprivation (LVD) and portal vein embolization (PVE) in patients scheduled to undergo liver resection.

Materials and methods: This retrospective cohort study included 59 patients who underwent either PVE (n = 28) or LVD (n = 31) in preparation for liver resection. The primary outcome was percent change in future liver remnant volume (FLRV). The secondary endpoints were degree of hypertrophy (DH) and kinetic growth rate (KGR).

Results: Low baseline FLRV and time interval in days between the procedure and follow-up imaging (Ti) positively impacted the primary and secondary endpoints in both groups. Percent change in FLRV was higher in the LVD group (52.8% ± 5.3) than in the PVE group (22.3% ± 3.0, P < .001). DH was also higher in the LVD group (15.4% ± 1.7) than in the PVE group (6.4% ± 0.9, P < .001). KGR did not differ significantly between groups (LVD, 0.54%/d ± 0.06; PVE, 0.35%/d ± 0.1; P = .239). When patients with a baseline standardized FLRV of >35% were excluded from the analysis, the LVD group demonstrated higher values than the PVE group in KGR (0.57%/d ± 0.06 vs 0.29%/d ± 0.05, P < .001), percent change in FLRV (64.2% ± 6.0 vs 25.9% ± 4.3, P < .001), and DH (15.4% ± 1.4 vs 6.6% ± 1.0, P < .001). No adverse events were noted in either group.

Conclusions: LVD appears to be safe and may be superior to PVE in inducing hypertrophy of future liver remnant in patients scheduled to undergo surgical resection.

The purpose of this study was to evaluate outcomes of the Denali inferior vena cava filter (Bard Peripheral Vascular, Tempe, Arizona). Five hundred patients had 508 filters placed between 2015 and 2022. Filters were retrieved at the study site in 284 patients: 159 (31.4%) filters were deemed permanent and 21 (4.1%) filters were retrieved at an outside hospital; 27 (5.3%) patients had outside-hospital follow-up without known retrieval and 17 (3.3%) patients were lost to follow-up. Initial retrieval at the study site was successful in 275 cases, while 7 cases had successful second retrieval attempts (99.3% overall success). Initial retrieval venogram showed clot in filter in 18 of 284 (6.3%) and an occluded cava in 12 of 284 (4.2%). Contrast-enhanced imaging was available in 79 patients without retrieval at study site: 7 of 79 (8.9%) had thrombus within the filter, 7 of 79 (8.9%) had caval thrombosis/occlusion/severe stenosis, and 1 of 75 (1.2%) had new nonocclusive caval thrombus. No filter fracture, clinically significant extravascular strut penetration, or migration was reported.

Pelvic venous disorders (PeVDs) are rarely considered as a cause of chronic pelvic pain in women being evaluated by nonvascular specialists. A Society of Interventional Radiology (SIR) Foundation-sponsored Research Consensus Panel addressing this issue identified multiple gaps in the literature and made recommendations to enhance the evidence. Since publication of these recommendations in 2019, significant progress has been made in developing the necessary tools to improve the ability to conduct rigorous clinical studies and advance the evidence supporting the diagnosis and treatment of PeVD. This report summarizes the 5-year impact of the panel's recommendations. The investment made by SIR Foundation to host a Research Consensus Panel on PeVD has facilitated enduring academic productivity related to this clinical issue.
